Scenario:
An oil well has been producing for 5 years. Its initial surface flowing pressure (FSP) was 2500 psi, and its current FSP is 1800 psi. The well's production rate has remained relatively constant over the years.
Task:
Based on the given information, analyze the potential reasons for the decline in FSP and suggest what actions could be taken to potentially improve production.
The decline in FSP from 2500 psi to 1800 psi over 5 years indicates a reduction in reservoir pressure. This could be due to several factors:
To improve production, potential actions include:
It's important to note that the specific actions required will depend on a comprehensive analysis of the well's production history, reservoir characteristics, and potential issues within the wellbore.
